S1820 – dual frequency shear wave DPC transducer 50 KHz / 300 KHz

Low-frequency ultrasonic transducer for transmitting or receiving the ultrasonic shear waves in two operating frequencies for ultrasonic pulse velocity testing and characterization of material properties.

A general-purpose low-frequency transducer with the nominal frequency of 50 KHz and 300 KHz for the dry-point-contact (DPC) excitation or acquiring ultrasonic shear waves in highly scattering materials (concrete, wood, stones etc.)

It can be used in ready-made housing with the Lemo00 plug or non-wired for self-tailored applications, e.g. for customization of transducer arrays by the customer.

The transducer can be driven by following ACS instruments:
